Abstract
This paper presents a CMOS output stage devised for driving heavy resistive loads. An operational amplifier of this type has been fabricated in a 3 μm double-polysilicon CMOS technology. With a supply voltage of ∓5 V and load of 470 Ω, the amplifier has a ∓4.6-V output swing and features a 60 mA short-circuit output current. Although simple, the proposed configuration enables the output transistors to be driven efficiently
